After setting things right, Lu Yi calmed down and began to fully comprehend the great array that Chen Yunzi had set up in Qilin City back then, he wanted to use this opportunity to break through to the sixth-order array mage in the shortest possible time, so as to add greater certainty to his next step.

Chen Yunzi only began to study the formation after stepping into the middle stage of spirit building, his qualifications were already very high, and after stepping into the middle stage of spirit building, he had a certain level of understanding of the way of heaven, so his practice of formation can be described as a thousand miles a day, and within a hundred years, he sang all the way directly from a layman to a sixth-order formation mage, which also became a legend in the Western Regions at that time, and even later there were people who wanted to follow Chen Yunzi but could not draw a tiger.

He had traveled in sandstone and had the idea of building a city on top of it, and when he told him about the idea, he really startled his men and thought it was not realistic. However, Chen Yunzi thought of it, and after observing a lot of sandstone, he chose the largest one, first arranged a number of small teleportation arrays under it to the top to transport people and materials, and then arranged a reinforced magic circle around its dozens of rock pillars, and then began to let his subordinates climb to the top of the rock to start building the city.

The sandstone where Qilin City is located is the largest one in the entire sandstone area, with a radius of nearly 100 miles, and after Chen Yunzi circled nearly half of the area on it to create the prototype of Qilin City, he successively arranged several magic circles in the city wall and its periphery to strengthen its protection ability and self-defense ability. These means are not only for man-made disasters, in the event of large-scale sandstorms and other natural disasters, after opening the city protection array, it can also ensure that the entire city is not buried by sand and dust, since the construction of the city, Qilin City has never been attacked by man, but has avoided several natural disasters that destroy the city, the most serious sandstorm has piled up nearly a foot high of sandstorm, which has continued to wreak havoc for four days, but it has not affected the city at all, and even the residents of the city from the beginning of the panic to later take the initiative to run outdoors to watch the external sandstorm scene through the defense array, and they also talked with each other very happily, and also laid the foundation for Qilin City to become famous in the Western Regions in the future。 It is precisely because of this that some people scoffed at Chen Yunzi's "crazy" idea of building a city on the top of the rock, and even played a score to see his jokes, and no one had ever planned to get involved in the sandstone area that belonged to the nature of chicken ribs, but after Qilin City stood for a hundred years, attracted a large number of surrounding residents to move to live, and urban trade was also in full swing, some people finally realized the benefits of this rock top, and began to compete to follow the example of Qilin City to occupy the surrounding sandstone with a decent area to establish their own cities. However, at this time, Qian Yunzi had already flown away, leaving only some of his subordinates responsible for managing Qilin City, and other forces did not have a formation mage like Qian Yunzi, and they could not invite high-level existences, so the cities built were much inferior to Qilin City in terms of scale and ability in all aspects, and even a few small cities had the tragedy of the destruction of the entire city due to natural and man-made disasters.

Chen Yunzi never went back after establishing Qilin City, he was also an advanced sixth-order array mage not long ago, and the sixth-order array arranged in Qilin City was not without the intention of trying it, if he looked at it from his current point of view, these arrays were already full of loopholes and unsightly, but for a low-level array mage, it was still a mountain-like existence, especially a formation mage like Lu Yi at the critical point of the fifth and sixth orders, and there were even more experiences and experiences that could be learned from it. When Chen Yunzi came to Lu Yi, he only roughly told him about his original intention of establishing a series of magic circles in Qilin City, and did not give him a detailed introduction to the formation and structure of these magic circles, everything was left to Lu Yi to explore and comprehend by himself, so that he could not only comprehend Chen Yunzi's formation experience, but also find what he wanted through enlightenment, which was a great benefit to Lu Yi.

Lu Yi first started from the bottom of Qilin City, observed each rock pillar one by one, found out the characteristics of the rock pillar, and then deduced it according to these characteristics, and chose the suitable magic circle with his own knowledge, and finally worked out the general idea, he turned back to observe the magic circle that Chen Yunzi had laid out back then, while contemplating, while comparing his own choices, Lu Yi found out his own shortcomings and studied them. Lu Yi stayed at the bottom of the sandstone where Qilin City was located for half a year, and he could now depict every rock pillar and the runes carved on it with his eyes closed, and he was really familiar with it, and even found a few small sandstones that were uninhabited and tried, trying to copy the magic circles that were arranged by Qian Yunzi to strengthen the sandstone. Lu Yi was not in a hurry, he gave up the study of these reinforcement arrays, and instead came to the outside of Qilin City, and began to comprehend those defensive arrays and attack arrays. It's been nearly a year since then, and Lu Yi pondered these magic circles almost and then went back to study the reinforcement circles below, and after switching back and forth a few times, Lu Yi finally felt that he could completely understand the essence of Chen Yunzi's arrangement of these magic circles. He no longer went to the scene to observe and comprehend these magic circles, but started a retreat in Qilin City, entered a quiet room, arranged a number of guards on the periphery, and took out a jade slip, which was handed over to Lu Yi by Chen Yunzi, which recorded his current evaluation and understanding of the magic circles in Qilin City, which was an evaluation of the strength of the sixth-order array mages from the height of the eighth-order formation master, and his comments pointed out a number of unsatisfactory places and some hidden worries, which made Lu Yi, who had always followed the sixth-order array mage's level down, feel that he was suddenly opened, and after figuring out all the problems, Lu Yi went out of the customs again and rushed to those magic circles, one by one, to corroborate the questions raised on the jade slip. After some confirmation, Lu Yi has a new understanding of the various magic circles in Qilin City, and now he looks at these magic circles again, and he no longer feels that they are so unfathomable as before, on the contrary, now it seems that there are many problems in these magic circles, so Lu Yi began a move that surprised all those who paid attention to him - to improve and transform the large and small magic circles in Qilin City!

Lu Yi stayed in Qilin City for thirteen years, and during these thirteen years, Lu Yi has always been doing one thing, which is to study the magic circle of Qilin City, when Lu Yi transformed and perfected all the magic circles in Qilin City in the fourteenth year, his formation level also advanced to the sixth order.

Lu Yi's successful advancement made all the people who paid attention to him excited, and those people sent by Chen Yunzi were all amazed by Old Man Chen's physiognomy skills, and after Lu Yi advanced to the sixth-order array mage, it was also the first time that those Chen Yunzi's subordinates who didn't know much about Lu Yi were truly impressed. The other sandstone forces are all hoping that Lu Yi can help them improve their own offensive and defensive systems and strengthen the rock pillars, they have all seen what Lu Yi has done over the years, especially when Lu Yi started to repair the first magic circle in Qilin City, it attracted a lot of attention, so when Lu Yi reached the sixth-order array mage, the entire sandstone area was also happy. All the leaders of the big and small forces who got the news spontaneously came to Qilin City to celebrate Lu Yi's successful promotion, while they were also waiting for Lu Yi to say when they would be able to help them arrange the magic circle, and even they had already secretly decided the order by drawing lots, which also saved Lu Yi from helping who first and then helping whom.

Lu Yi himself was also very happy, this sixth-order array mage had stuck himself for so many years, and now he finally got what he wanted, and a big stone in his heart had fallen to the ground. Seeing that so many "test subjects" were waiting for him to practice his hands like lambs to the slaughter to consolidate his formation cultivation, Lu Yi waved his big hand very arrogantly, "Go back and wait with peace of mind, master, I will start to help you set up the formation after a few days, you just need to prepare delicious food and wine to serve my stomach." ”

The minds of the various forces went back happily, but as soon as they left on the front foot, a heavyweight came to Qilin City on the back foot, and even the human butcher and the ninth-order late-stage female cultivator who was secretly responsible for protecting Lu Yi had never appeared were alarmed, because the person who came was none other than Sima Hongqian, the founder of the Eastern Expansion Kingdom and the great monk of the late stage of soul building at the same level as Chen Yunzi.

Sima Hongqian suddenly appeared in the Chunhui Hall where Lu Yi was staying, and Lu Yi was discussing with Tu Zi what to do next, because at this point, the matter of Qilin City was basically over. After taking the entire sandstone area and creating a large base, whether Lu Yi wants to go to the other places provided by Chen Yunzi or start his own fame on the spot in order to make a name for himself, it will be up to Lu Yi to weigh it. Of course, it may take a few years to agree to help those surrounding forces to set up formations, but Lu Yi has already thought about it, asking them to find more formation mages of the fourth order, Lu Yi plans to personally design the formation plans of each force and then hand over the hands-on work to those low-cost formation mages to do, and he also gives his own name to guide and promote his juniors, which not only earns fame but also saves energy, why not?

Lu Yi was talking to the butcher about his wishful thinking, but he was taken aback by a burst of applause, and the two of them realized that there was a monk with a majestic middle-aged man in the room, and while applauding Lu Yi's cunning, he leaned over to the two with a smile. Human Tuzi naturally knew the person, he didn't know the other party's intentions, so his expression was unusually tense, the space fluctuated, and a woman with a mediocre appearance but a very hot figure also appeared on Lu Yi's side, with the aura of the late ninth order fully displayed, and the human butcher protected Lu Yi in the middle.
